Wolfram Syndrome (WFS) is a debilitating autosomal recessive neurodegenerative disorder characterized by juvenile onset insulin dependent diabetes mellitus (DM) and optic atrophy (OA) as well as a number of neurological and endocrine complications that result in early death due to respiratory complications. Previous research has mapped Wolfram syndrome to chromosome 4p16.1 and the disease has been attributed to mutations in the WFS1 gene affecting the WFS1 protein (wolframin), an ER membrane glycoprotein that plays an important role in the unfolded protein response (UPR) and in intracellular Ca2+ homeostasis. An additional locus for WFS on chromosome 4q22-24 was identified by linkage …
